Question

A lawn in the shape of a rhombus has a base of 12 m and a height of 10 m. If the rate of tiling is 12 per sq. m, find the total cost of tiling the lawn. ​

Answer 1

Answer:

Rs 10500

Step-by-step explanation:

Sides of the triangle are a=50m,b=65m,c=65m

Area of triangle, by Heron's formula =

s(s−a)(s−b)(s−c)

where,

s=

2

a+b+c

s=

2

50+65+65

s=90

Area of triangle =

90(40)(25)(25)

Area of triangle = 1500m

2

Cost of laying grass = Area ×7

Cost of laying grass =1500×7

Cost of laying grass = Rs 10500
