Problem |
An isosceles triangle has a perimetŠµr of 45 centimeters, and its base has a length of 6 centimeters. Each of the other two sides has a length of cm. |
|
2 |
Step |
The perimeter of an isosceles triangle(P) is given, |
45 cm |
3 |
Step |
The base length of an isosceles triangle is given,(b) |
6 cm |
4 |
Formula |
Perimeter of an Isosceles triangle |
P = 2a + b |
5 |
Step |
Substitute the values we get |
45 = 2a + 6 |
6 |
Step |
subtract 6 on both sides |
45 - 6 = 2a + 6 - 6 |
7 |
Step |
After subtraction, the value we get |
39 = 2a |
8 |
Step |
Divide 2 on both sides |
\$39/2\$ = \$(2a)/2\$ |
9 |
Step |
After simplification, the value we get |
a = 19.5 |
10 |
Step |
The two side lengths of an isosceles triangle are 19.5 cm. |
