Find the area of the following polygons:

84 m²

Step-by-step explanation:

The polygon is composed of a rectangle and a triangle.

area of rectangle = 12 × 4 = 48 m²

area of triangle = × 12 × (10 - 4) = 6 ×6 = 36 m²

Total area = 48 + 36 = 84 m²

32

step-by-step explanation:

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
