Finding the Missing Side Length of a Composite Shape

Click For Summary

Homework Help Overview

The discussion revolves around finding the missing side length of a triangle within a composite shape, specifically focusing on calculating the area of both a rectangle and a triangle to determine the total area of the figure.

Discussion Character

  • Exploratory, Conceptual clarification, Problem interpretation

Approaches and Questions Raised

  • Participants discuss the formulas for calculating the area of a rectangle and a triangle. Questions are raised about the necessity of finding the length of one side of the triangle when the base and height are already known.

Discussion Status

Some participants have provided guidance on directly calculating the area of the triangle using the known base and height, which has led to a realization for one participant about the approach to take. The discussion reflects a productive exchange of ideas without reaching a final consensus.

Contextual Notes

Participants mention specific dimensions for the rectangle and triangle, including a base of 8 m and a height of 5 m, while also noting the overall goal of finding the total area of the composite shape.

Homework Equations


A = l x w
A = hbb / 2

The Attempt at a Solution


To find the area of a rectangle you would use the formula "A = L x W". In this case A = 14 x 8 which is eual to 112, Now all i need is the area of the triangle and then i add them together and that will be the area of the whole figure.

So i know we have the height of the triangle is 5
Also the part i colored yellow is 8 m long.

So my question is how can i find the length of 1 of the sides of the triangle.

Why would you need to find that?

I need to find the area of that triangle, that way i can find the whole area of that composite shape.

for area of that triangle you already have the base ( 8m) and height (5m), so you don't need to calculate other sides, you can directly calculate the area.
 
OMG I totally didn't even think about that...... face palm:doh:. sahil you just cleared my mind, man I am so in a blrr today. anyway i now know what to do.
 
Thanks m8 :)
