Question 148: Basic Numeracy
A rectangle has a perimeter of 50 metres. If its length is 13 metres more than its breadth, then its area is
a124 m²
b144 m²
c114 m²
d104 m²
AnswerThe answer is (c).
A perimeter of 50 m gives length + breadth = 25. The length is 13 m more than the breadth, so 2 x breadth + 13 = 25, which gives breadth 6 m and length 19 m. The area is 19 x 6 = 114 m2.
Why each option is right or wrong
- (a) The area is 19 x 6 = 114 m2, not 124.
- (b) The area is 114 m2, not 144.
- (c) Right: 19 x 6 = 114 m2.
- (d) The area is 114 m2, not 104.
