Answer:

A) 3 sq cm

Explanation:

Look at the picture.

The formula of an area of a rectangle:

A = wl

w - width, l - length

We have two rectangles:

Rectangle 1:

1cm × 2cm

A₁ = 1cm × 2cm = 2cm²

Rectangle 2 (square):

1cm × 1cm

A₂ = 1cm × 1cm = 1cm²

The area of a shape:

A = A₁ + A₂ → A = 2cm² + 1cm² = 3cm²

What is the area of the shape ? A) 3 sq cm B) 4 sq cm C) 6 sq cm D) 9 sq cm-example-1
