Question

perimeter of isosceles triangle with base twice the sum of equal sides is 54cm find the length of equal​

Answer 1

Answer:

Use a similar formula, Perimeter = 2A + B, to find the perimeter of the isosceles triangle, where A and B are the length of the legs and base. Solve for area just as you would any other triangle using the formula Area = 1/2 B x H, where B is the base and H is the height.

Step-by-step explanation:

Answer 2

Answer:

Perimeter = 54cm

x + x + 2x = 54

x = 54/4

x = 13.5 is the length of the two sides.

the base is equal to 27 cm.
