Question

The perimeter of a rectangle whose one side measure 20 m and the diagonal is 29 m (a) 82 m (b) 78 cm (c) 98 m (d) 88 m

Answer 1

diagonal= √square of side a+ square of side b
so, another side= √29×29-20×20
= √841-400
=√441=21
perimeter=2(l+b)
=2(20+21)=2×41=82m.

Answer 2

Answer:

Option C :- 98 M

Step-by-step explanation:

Perimeter of Rectangle = 2 x (Length + Breadth)

                                       = 2 x (20 + 29)

                                       = 2 x 49

                                       = 98 M
