Question

perimeter of the rombus is 100m and its diagonal is 40m Find the area of rombus​

Answer 1

Answer:

636 m ^2

Step-by-step explanation:

Perimeter (P) = 100m

Diagonal1 (D1) = 40m

Since, perimeter = 100m

Hence, one side = 100m/4 = 25m

One side = 25m

diagonal = 40m => 1/2 of diagonal = 20m

By Pythagoras theorem,

The other diagonal = √(25)^2 - (20)^2

= √255 = approx. 15.9

The area is

1/2 * D1 * D2

1/2*40*31.8

636 m ^2

Therefore, the answer is 636 m ^2.

Answer 2

Step-by-step explanation:

Perimeter of rhombus= 4 × a

100= 4 × a

a = 100/4

a = 25

Area of rhombus=

1/2×d1×d2

1/2×40×25

1/2×1000

500
