Question

podem me ajudar aqui ?
como se faz esses calculos e quais sao as respostas ? das 2

Answer 1

h²=m.n
6²=8n
8n=36
n=36÷8
n=4,5cm

a=m+n
a=8+4,5
a=12,5cm

b²=am
b²=8.12,5
b²=100
b=√100
b=10cm

c²=an
c²=(12,5).(4,5)
c²=56,25
c=√56,25
c=7,5cm

b)
$Area= \frac{b\times h}{2} = \frac{12,5\times6}{2} =12,5\times3 \\ \\ Area=37,5cm^2$
