Question


a square painting is surrounded by a 2.5cm frame. if the total are of the painting plus frame is 3600 sq cm, find the dimensions of the painting.
what are the dimensions? i forgot how to find the dimensions. please help me .
Since the painting is square, the length of each side of the painting, a, is such that

(a + 5)^2 = 3600 cm^2
a + 5 = 60 cm
a = 55 cm

The "5" in that equation is the width of two frame borders that must be added to the painting dimension
what's ^2 ? :)
could you do it in a RESC form?
No to the RESC form, whatever that is.
The logic of the method should be apparent.

^2 means "squared". The ^ in front of the 2 means that the 2 is an exponent.
representation, equation, solution and conclusion.
is that true? the answer, how old are you two?
