Question

Q4. The dimensions of a rectangular sheet of metal are 9.96m by 5.08 m. Find

a. the perimeter of the metal, correct to 1 significant figure
b. the area of the metal, correct to the nearest 0.1 m2

Answer 1

a) 30m

b) 50.6m²

Explanation:

Perimeter = 2(length + width)

= 2(9.96 + 5.08)

= 30.08 m

Area = length × width

9.96 × 5.08

50.5968 m²
