Question

The base of an isosceles triangle is 3/4 cm. The perimeter of the triangle is 41/20 cm. The length of either of the remaining equal sides is

Answer 1

Solution

Given :-

• The base of an isosceles triangle is 3/4 cm.
• The perimeter of the triangle is 41/20 cm

Find :-

• The length of either of the remaining equal sides is

Explanation

Let,

• Side of equal two side of isosceles triangle is x

Using Formula

★ Perimeter of isosceles triangle = sum of all side

Keep all above values

➡ 41/20 = 3/4 + x + x

➡ 2x = 41/20 - 3/4

➡ 2x = (41-15)/20

➡2x = 26/20

➡x = 26/(20 × 2)

➡x = 13/20 cm

Hence

• Side of two equal side be x = 13/20 cm

Answer 2

Answer:

0.65 cm

Step-by-step explanation:

The base of an isosceles triangle is 3/4 cm. The perimeter of the triangle is 41/20 cm.

Perimeter of isosceles triangle = Sum of it's all sides

Given one side is 3/4. Assume the other two sides are x.

Substitute the values,

→ 41/20 = 3/4 + x + x

→ 41/20 = 3/4 + 2x

→ 41/20 - 3/4 = 2x

→ (41 - 15)/20 = 2x

→ 26 = 40x

→ 26/40 = x

→ 0.65 = x

Hence, the ngth of either of the remaining equal sides is 0.65 cm.
