Question

if equal ade of isoceles right angled triangle is 12cm then find area​

Answer 1

Answer:

4.9

Step-by-step explanation:

Let ABC be the given triangle right angled at B with AB=BC — (1)

AREA OF TRIANGLE = $12cm^{2}$

Area of triangle = $\frac{1}{2}$bh

==》 $\frac{1}{2}$ × BC × AB = 12

==》$\frac{1}{2}$ × BC × BC = 12

==》$\frac{1}{2}$ × $BC^{2}$ = 12

$BC^{2}$ = 24

BC = 4.9CM (APPROX )

Length of the base= 4.9 cm (approx )
