Answer:
The dimensions of rectangle are 230 in by 59 in
Step-by-step explanation:
The question in English is
What are the dimensions of a rectangle with a perimeter equal to 578 inches, if its length is 6 inches less than 4 times its width?
Let
x-----> the length of rectangle
y----> the width of rectangle
we know that
The perimeter of rectangle is equal to
P=2(x+y)
P=578 in
so
578=2(x+y)
289=x+y -----> equation A
x=4y-6 -----> equation B
substitute equation B in equation A
289=(4y-6)+y
5y=295
y=59 in
Find the value of x
x=4y-6 -----> x=4(59)-6=230 in
therefore
The dimensions of rectangle are
230 in by 59 in
