Question

Find the area of a right angled triangle whose one side is 7 cm long and length of hypotenuse is 25cm.​

Answer 1

Answer:

hey your answer is as follows

pls mark it as brainliest

Step-by-step explanation:

so let the required right angled triangle be triangle abc right angle at b

so here ab=7cm and ac=25cm

so by using pythagoras theorem

we get bc=24cm

here negative value is also possible

but as dimensions length are never negative bc=-24 is absurd

hence bc=24cm

now as we know that area of right angled triangle

=1/2×product of sides making right angle

so area of triangle abc=1/2×bc×ab

=24×7/2

=84cm.square

hence area of right angled triangle is 84cm.square
