Answer:side one is 8cm
Side 2 is 8cm
Side 3 is 15 cm
Step-by-step explanation:
The perimeter of a shape is the distance around the shape. The perimeter of a triangle is the sum of the sides of the triangle.
Let x represent the length of side one and side 2. Since they have equal length, the sum of their length is x + x = 2x cm
Side three is one cm shorter then twice the length of side one. This means that the length of side three would be 2x - 1
The perimeter of a triangle is 31cm. Therefore,
2x + 2x - 1 = 31
4x - 1 = 31
4x = 31 + 1 = 32
x = 32/4 = 8 cm
Side three = 2×8 - 1 = 16 - 1 = 15
Answer:
P = 6.4 m
Step-by-step explanation:
Hello,
The perimeter is the sum o each side of that square, so:
Psquare = 4*(lenght of side)
P = 4*(1.6m)
P = 6.4 m
PD: PI IS NOT NECESSARY, WORKS ONLY FOR CIRCLE
Best regards
Add all of the numbers together , and then divide by how many numbers your adding up. in this case you would divide by 8.
