Perimeter and Area Solution4





In this page perimeter and area solution4 we are going to see solution of some practice questions.

Question 4 :

Which has larger area? A right triangle with the length of the sides containing the right angle being 80 cm and 60 cm or a square of length 50 cm.

Solution:

Breadth of right triangle = 80 cm

Height of right triangle = 60 cm

Length of each side of square = 50 cm

To find which area is larger we have to find areas of both plots separately.

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

                                      = (1/2) x 80 x 60

                                      = 80 x 30

                                      = 2400 m²

Area of square field = a ²

                             = (80)²

                             = 80 x 80

                             = 6400 m²

From this we come to know that area of square field is more than the right triangle field.
