Area of Composite shapes.

Homework Statement

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?

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.

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. sahil you just cleared my mind, man I am so in a blrr today. anyway i now know what to do.
