Question

find the permiter area length of the diagonal of a square whose sides are a) 12cm math​

Answer 1

Answer:

648 cm2

Step-by-step explanation:

a square area is

L*L

12*12=144

so the diagonal will be 1/2 bh =1/2 (36)(36)=648

Answer 2

Step-by-step explanation:

given side is 12 cm

perimeter is 4× side

4×12 =

perimeter48 cm

area = side ²

12²

area= 144cm

we can find diagolal by pythagoras theorem

s²+s²=hypotenuse ²

12²+12²= diagonal ²

288= diagonal ²

diagonal=√288

= √144×2

diagonal=12√2
