The perimeter of the isoceles triangle is 54. The ratio of the leg to the base is 7:4. Find the length of the base

Norma-Jean [14]

9514 1404 393

Answer:

12 units

Step-by-step explanation:

The ratio of the base to the other sides is ...

4 : 7 : 7

The perimeter is a total of 4 +7 +7 = 18 ratio units, so each ratio units stands for 54/18 = 3 length units.

The base length is then ...

(4 ratio units)(3 length units/ratio unit) = 12 length units
