Question

(C) isosceles triangle having equal sides as 40 cm and third side as 20 cm
There is a rectangular lawn 10 m long and 4 m wide in front of Meena's
house as shown in figure. It is fenced along the two smaller sides and
one longer side leaving a gap of 1 m for the entrance. Find the length of
fencing
Find the side of a square whose perimeter is 124 cm​

Answer 1

Answer:

17 m

Explanation:

length of the lawn = 10 m

breadth (width) of the lawn = 4 m

fence required for the two smaller sides= 4 m + 4 m= 8 m

Fence required for the longer side:

length of the rectangular lawn - length of gap=

= 10 m - 1 m = 9 m

Total length of fencing =

= fence required for the two smaller sides + fence required for the longer side

= 8 m + 9 m = 17 m
