What is the perimeter of a rectangle, in units, if y=21/2 and the length is 2y+1?

65 units

Step-by-step explanation:

Assume y is the breadth of the rectangle, since length is given.

y = breadth = 21 ÷ 2 = 10.5 units

length = 2(10.5) + 1 = 22 units

Therefore,

Perimeter = 2 (length + breadth)

= 2 (22 + 10.5)

= 65 units

may i see the picture? it would a lot, xox

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!
