Question

the area of an isosceles triangle is 300 CM square the height of the triangle is 15 cm find the perimeter of the triangle

please telll whole solution

​​

Answer 1

Step-by-step explanation:

Draw a right iscoceles triangle ABC

Height=15cm,Area=300cm^2

let two sides of triangle be y or base also

So,

we know that,

1/2*y*h=300cm^2

1/2*y*15=300cm^2

y=300*2/15

y=40cm

so,

perimeter =(40+40+15)cm=95cm

Answer 2

Answer:

90cm

Step-by-step explanation:

A=bh/2. {h is height}

300×2=b×15. {b is base}

b=40

b/2=20=B

B^2+P^2 = H^2. {H is other side)

20×20+15×15=H×H

H=25

perimeter = H+H+B

= 25+25+40

=90
