Question

Section B (Each question carries 2 marks.)
4. A rectangle is made with 18 m long rope. If the length of the rectangle is 5 m, find its breadth​

Answer 1

Answer:

the perimeter of rect. is 18m

so lenth is 5m

therefore

5+x=18

x=18-5=13

hence

b=13m

Answer 2

length of rope =18 m

length of rectangle =5 m

WKT,

a rectangle's opposite sides are equal

if length = 5m opposite side is also 5m

5+5=10m

total length of rope - 10m

18 -10m

= 8m
