- [Equality Property] Square root both sides:
So l=8 and 8+2.5=10.5
which means the length of the second rectangle is 10.5
w=6.2 and 6.2-1.4=4.8
which means the width of the second rectangle is 4.8
The formula for area of a rectangle is length×width
10.5×4.8=50.4 so the area of the second rectangle is 50.4 squared
Step-by-step explanation:
I think that is the right answer I hope ut helps
50(30%) = 15
50 - 15 = 35
