Answer:
The measure of the fourth side is .
Step-by-step explanation:
Given as :
The Perimeter of rectangular store = ( 10 + ) inches
The measure of three sides of rectangle = ( 8 + ) inches
So, The measure of three sides = length + breadth + length
I,.e 2 L + B = ( 8 + ) inches .....1
∵ perimeter = ( 10 + ) inches
So , 2 L + 2 B = ( 10 + ) inches
Or, 2 L + B + B = ( 10 + ) inches
Or, ( 8 + ) + B = ( 10 +
)
or, B = ( 10 + ) - ( 8 +
)
Or, B = 10 - 8 + ( ) -
or, B = 2 +
or, B = 2 +
∴ B = =
Hence The measure of the fourth side is . Answer
