In this page perimeter and area solution2 we are going to see solution of some practice questions.

**Question 2 :**

The cost of a right triangular land and the cost of a rectangular land are equal. Both the lands are adjacent to each other. In a right triangular land the adjacent sides of the right angles are 30 m and 40 m. The dimensions of the rectangular land are 20 m and 15 m. Which is best to purchase?

**Solution:**

Let us take a right angle triangle ABC,in which right angle is at B.In a right triangular land the adjacent sides of the right angles are 30 m and 40 m.

AB = 30 m and BC = 40 m

The dimensions of the rectangular land are 20 m and 15 m.

Length of rectangular land = 20 m

Width of rectangular land = 15 m

Cost of right angle triangle ABC = Cost of rectangular field ABCD

To find which purchase is best we need to find the area of both lands separately,

Area of right angle triangle ABC = (1/2) **x** b **x** h

= (1/2) **x** 40 **x** 30

= 40 **x** 15

= 600 m²

Area of rectangular field = Length **x** Width

= 20 x 15

= 300 m²

**Since area of right triangle is more we can choose right triangle field for best purchase. **
