What is the product of -4 1/2 and 2 1/2and i need the answer is a mixed number

The product would be -11 1/4.

BECAUSE

You convert mixed numbers to fraction

−9/2 × 5/2

Multiply the fraction and that would give you -45/5

By simplifying -45/5, the answer is -11 1/4

HOPE THIS HELPS :)

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2

the answers might not be correct use at own risk
