Please please help me I need to learn this for my school tmr thank u very much if you do help me !!
galben [10]

Answer:

Step 1 :

Split the figure into 3 parts

part 1: triangle with base = 7 + 2 + 6 = 15in, height = 7in

part 2 : Rectangle with breadth = 3 + 6 + 2= 11in and length 8in

Part 3 :Rectangle with breadth 2in  and length 9in

Step 2 :

find the area of each part

Area of part 1

             \frac{1}{2}  * base * height = \frac{1}{2}*15*7 = 52.5in^{2}

Area of part 2

             length * breadth = 11*8 =88in^{2}

Area of part 3

              length * breadth = 2*9 =18in^2

Total area = 52.5 + 88 + 18 = 158.5 sqaure inches
