Find the area of the composite figure.

atraingle =

7.5 yd2
21 yd2
30 yd2
15 yd2

Part a) The area of the composite figure is

Part b) The area of the triangle is  

Step-by-step explanation:

we know that

The area of the composite figure is equal to the area of rectangle plus the area of triangle plus the area of trapezoid

Step 1

Find the area of rectangle

Step 2

Find the area of triangle

Step 3

Find the area of trapezoid

Step 4

Find the area of the composite figure

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.

(w – 2.5)(w + 2.5)

(–4v – 9)(–4v + 9)
