Use the Pythagorean theorem:
Step-by-step explanation:
4:3
4+3=7
4x + 3x= 7x
7x is the total sq.cm which is 300
7x= 300
x= 300/7
= 42.8
length= 4x
= 4 × 42.8
= 171.42
breadth= 3x
= 3 × 42.8
= 128.4
So this is integers. What you are going to do is 54 - - 34 which equals positive 20 because 54 is higher than 34 which is negative, and 54 is positive. So the answer is going to be 20$.
-3 is the answer for this
