Question

IN A ISOCELES TRIANGLE, THE LENGTH OF THE EQUAL SIDES EXCEEDS THAT OF THE BASE BY 4.5 CM. THE PERIMETER OF THE TRIANGLE IS 34.5 CM. FIND THE LENGTH OF THE SIDES OF THE TRIANGLE.​

Answer 1

Answer:

Let the base be x

so the lenght of the equal sides = 4.5+x and 4.5 +x

perimeter is 34.5

now

4.5+x+4.5+x+x=34.5

9+3x=34.5

x=8.5

so

base =8.5cm

equal side =8.5+4.5=13

8.5+4.5=13

Answer 2

Answer:

Given,

base of a triangle=4.5 cm

perimeter of a triangle =34.5 cm

A/Q

length of the two side be x

x+x+4.5 = 34.5 cm

2x+4.5 = 34.5 cm

2x = 34.5 - 4.5

2x = 30cm

x = 30 cm ÷ 2

x = 15 cm

for check

put the value of x = 15 cm

x+x+ 4.5 cm

15 + 15 + 4.5 cm = 34.5 cm

Step-by-step explanation:
