Answer:
87 cm²
Step-by-step explanation:
there is 1 triangle and 1 rectangle in the diagram. so you have to find the area of the both polygons and sum up to find the total area of polygon
area of triangle formula:
1) area of triangle AED
base = 12 cm
height = 4.5 cm
area:
area of rectangle formula:
2) area of rectangle ABCD
length = 12cm
height = 5 cm
area:
3) area of whole polygon
= area of triangle AED + area of rectangle ABCD
= 27 cm² + 60 cm²
= 87 cm²
Answer:
