Question

find the cost of landscaping a garden which is in quadrilateral shape at rupees 5 per square meter if one of the diagonal is given as 18 m and the altitudes drawn to that diagonal are 12m and 14meters?​

Answer 1

Step-by-step explanation:

Area of quadrilateral =sum of area of two triangles form by the diagonal

Suppose the diagonal as base we have height of the formed triangles

$area = \frac{1}{2} \times 18 \times 12 + \frac{1}{2} \times 18 \times 14$

$= 108 + 126 = 234$

Cost of landscaping =234x5=₹1270
