Answer 1

Answer:

Length = 120 cm

Area = 3,600 sq. cm

Step-by-step explanation:

30 + 30 = 60. So, the length of the rectangle is (300 - 60) ÷ 2.

(300 - 60) ÷ 2 = (240) ÷ 2 = 120. Hence, the length of the rectangle is 120 cm.

120 cm x 30 cm = 3,600 cm. Hence, the area of the rectangle is 3,600 sq. cm.
