Find the area of a rectangle ABCD (with sides 1cm and 7cm) and a square KMOE (with a side of 3 cm)

Given:

length = 1 (cm);

width = 7 (cm);

S ABCD =? (cm²).

The area of a rectangle is equal to the product of its sides and is calculated by the formula

S = a * b, where a is the length, b is the width, S is the area.

1) S = 1 * 7 = 7 (cm²)

Answer: 7 cm² is the area of the rectangle ABCD.

Given:
a = 3 cm;
S KMOE =? cm².
The task of calculating the area of a square. The area of the square is calculated by the formula:
S = a² – where, a is the side of the square.

1) S = a² = 3² = 9 (cm²).

Answer: 9 cm² area of the KMOE square.
