Question

Solve the problem by writing an inequality.

If the perimeter of a rectangular picture frame must be less than 200 in., and the width is 36 in., what must the height h of the frame be?

A. h < 64 in.

B. h > 128 in.

C. h > 64 in.

D. h < 128 in.

i want to know how to actually do this myself ._.

Answer 1

The perimeter is P = 2h + 2w, for height h and width w. We know that w=36 so P = 2h + 72. Also, P<200 so 2h+72<200 and therefore 2h<128 so h<64.

Answer 2

thank youuu. that makes more sense

Answer 3

Welcome :)
