Question

solve q. 7 and 8 .......

Answer 1

my dear friend i am solving q no 7. please see it i am giving the photo and of q no. 8 also . i am writing question no . 8

so ans= you have the base and perpendicular equal so let both b as they are equal . so make a equation that is 1/2×b×b=200
=b*2=400
b=underroot 400
b=20 , so now put it and apply pythagoras to find hypotenuse that is 20*2+20*2=800
=underroot 800 that is 20root 20 .

hope you get what i said .
