Question

Rocco places four congruent squares side by side in a row. The length of one side of a square is 2cm. What is the perimeter and the area of the larger rectangle rocco makes?

Answer 1

A= 16

P=20

Explanation:

Each square is 2cm in length. 4 squares in a row would then be 4*2 = 8 cm in length. The width would remain 2 cm.

Area: A=l*w=8*2= 16 square cm

Perimeter: P=2l+2w=2*8 + 2*2 = 16+4=20 cm
