Question

A table cloth was used to cover a rectangular center table, leaving an uncovered portion of 20 CM round it. If the table is 11 1/2 m by 2/4 m, calculate the area of the table cloth

Answer 1

Answer:

10.71 m²

Step-by-step explanation:

Convert 20 cm to m:

20 cm = 0.2 m

Find the dimension of the table cloth:

Length = 11 1/2 + 0.2 + 0.2  = 11.9 m

Breadth = 2/4 + 0.2 + 0.2 = 0.9 m

Find the area of the table cloth:

Area = Length x Breadth

Area = 11.9 x 0.9 = 10.71 m²

Answer: The area is 10.71 m²

Answer 2

length of covered part ( table cloth)

= 11.5 - 0.2

= 11.3 m.

width = 0.5 m

so area of table cloth is

= length × width

= 0.5 × 11.3

= 5.65 m²
