in a figure, a triangle is removed from a square of sides 9 m . find area of figure when one side is 2.5m and other 3m
Answers
Step-by-step explanation:
The area of the figure is 40.5 m².
Step-by-step explanation:
Given, square of side = a = 9 m
Height of the triangle = h = 9 m
Base of the triangle = b = 9 m
Area of the triangle = \frac{1}{2}\times b\times h21×b×h = \frac{1}{2} \times 9 \times 921×9×9 = 40.5 m²
Area of the square = a² = 9² = 81 m²
Area of the figure after triangle is removed from a square
= Area of the square - Area of the triangle
= 81 - 40.5 = 40.5 m²
Hence, the area of the figure is 40.5 m².
Answer:
The area of the figure is 40.5 m².
Step-by-step explanation:
Given, square of side = a = 9 m
Height of the triangle = h = 9 m
Base of the triangle = b = 9 m
Area of the triangle = \frac{1}{2}\times b\times h

×9×9 = 40.5 m²
Area of the square = a² = 9² = 81 m²
Area of the figure after triangle is removed from a square
= Area of the square - Area of the triangle
= 81 - 40.5 = 40.5 m²
Hence, the area of the figure is 40.5 m².
