Answer:
1.) The perimeter of a rectangular garden is 10 sq meters and its length is 3 meters longer than its width. What is the length of the rectangular garden?
B. 5m
2.) The lengths of the two sides of a rhombus are 5x - 11 and
2x + 25, find its perimeter.
A. 70
Step-by-step explanation:
Answer:
1. A. 4m
Solution:
Let
x - Width
x+3 - Length
2(x+3)+2x = 10
2x+6+2x = 10
4x = 10-6
4x = 4
x = 1
Length = x+3
= 1+3
= 4
2. C. 196
Solution:
5x-11 = 2x+25
5x-2x = 25+11
3x = 36
x = 12
Side = 2x + 25
= 2(12) + 25
= 24 + 25
= 49
Perimeter = 4(Side)
= 4(49)
= 196
