Question

Find the area of the irregular figure. Round to the nearest hundredth.

Answer 1

The answer is 137.5in^2

Answer 2

137.5 in^2

Explanation:

So, this is basically a rectangle and two right-sides triangles.

First the rectangle: Formula is A=wl

Replace the Values: A = 14*7 98 in^2

Then we solve for the two right-sides triangles.

A= 1 /2a h= 1 /4 b ^2 sin (2 θ )

Top trinangle= A = 25.5 in^2 (height 7 in base 7 in)

Bottom Trinagle A = 14 in^2 (height 7 in base 4 in)

Add results:

98+25.5+14 = 137.5 in^2
