the perimeter of a rectangle measures 49 cm. one side is 7 cm longer than the other and 5 cm shorter than the third . find the length of each side of the triangle .
Answers
• Perimeter of rectangle = 49 cm
• Let one side of rectangle be M cm.
» One side is 7 cm longer than the other.
• Let second side of rectangle be (M - 7) cm
» And the third side is 5 cm shorter.
• Let third side be (M + 5) cm
______________________________
A.T.Q.
Perimeter of rectangle = Sum of all sides
=> M + M - 7 + M + 5 = 49
=> 3M - 2 = 49
=> 3M = 49 + 2
=> 3M = 51
=> M = 17
_______________________________
Length of one side of rectangle = M = 17 cm
Length of second side of rectangle = M - 7 = 17 - 7 = 10 cm
Length of third side of rectangle = M + 5 = 17 + 5 = 22 cm
_____________ [ANSWER]
Answer:
Perimeter of rectangle = 49 cm
• Let one side of rectangle be M cm.
» One side is 7 cm longer than the other.
• Let second side of rectangle be (M - 7) cm
» And the third side is 5 cm shorter.
• Let third side be (M + 5) cm
A.T.Q.
Perimeter of rectangle = Sum of all sides
=> M + M 7+ M + 5 = 49
=> 3M - 2 = 49
=> 3M = 49 + 2
=> 3M = 51
=> M = 17
Length of one side of rectangle = M = 17 cm
Length of second side of rectangle = M - 7 = 17 -
7 = 10 cm
Length of third side of rectangle M + 5 17 +5 = 22 cm
