Answer 1

Hello!

A1 = green

A2 = yellow

A3 = red

A1 = 15m * 3m = 45m²

A2 = (15m - (6m + 6m)) * 4m = 3m * 4m = 12m²

A3 = 15m * 3m = 45m²

A = A1 + A2 + A3

= 45m² + 12m² + 45m²

= 102m²

Answer 2

b. 102 m²

Explanation:

In order to find the area of shape.

Let's separate it into three rectangle.

We know that

Area of rectangle: Length*breadth

Using this

Area of left rectangle=15*3=45 m²

Area of middle rectangle=4*(15-6-6)=12 m²

Area of right rectangle= 15*3=45m²

Now

Total Area of shape= 45m²+12m²+45m²=102m²
