Hi, someone can explain this to me? i cant find the perimeter or the angle without the but i cant find the widht without the angle,

Hi!

You don’t need to find any measurements because the question says “solve in terms of x.” So basically instead of putting numbers in your equations, you would put the expressions given to represent height and width (x and x + 3).

To solve the problem, you would use your regular formulas for finding the area and perimeter of a rectangle (A=l x w and P = sum of all four sides). Instead of using numbers put in the equations and simplify.

P = x + x + x + 3 + x + 3
= 4x + 6

A = lw
= (x)(x + 3)
= x^2 + 3

I think these solutions are right, haven’t dealt with these problems in a long time.

Multiply 9 and 67. then multiply 3 with 67. lastly the answer that you got for 9x67 is to be subtracted by the answer you got for 3x67
