Question

if the area of the right angle triangle formed by two in adjacent sides of a diagonal of a square is 40.5 square metre then find the perimeter of the square

correct answer Brillianist step by step ​

Answer 1

Step-by-step explanation:

See

1/2 (side)^2 = 40.5

(side)^2 = 90

side = √(90) = 3√10

so required perimeter is 4(side)

= 4(3√10)

= 12√10

ans

Answer 2

Answer:

Perimeter- 36cm

Step-by-step explanation:

Area of right angled traingle=

½ ×side×side

½(side²)

Therefore, By the problem,

=>½(side²) =40.5 cm²

=>side²=40.5÷½

=>side²= 81

=>side=√81

=>side=9cm

Therefore, perimeter of square= 4×side

= (4×9) cm

= 36cm(ans)
