Pleh backwards and you will know what I’m trying to say

Area of triangle = 144 sq.in

Area of rectangle = 312 sq.in

Area of whole figure = 456 sq.in

Step-by-step explanation:

area of truangle =

area of rectangle =

area of whole fig. = 312 + 144 = 456 sq.in

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36
