Question

47. If the length of one of the diagonals of a rhombus is 32 cm. and its perimeter is
80 cm. then find its area,
a) 768 cm b)384 cm. c) 400 cm. d) 412 cm​

Answer 1

0ne diagonal of rhombus =36cm

Perimeter of rectangle=80cm

perimeter of Rhombus =4×Side

80cm = 4×side

side=80/4

side= 20

So another digonal=20cm

Area of rhombus = 1/2×d1×d2

1/2×32×20

= 320cm^2
