Arectangular strip of paper has a perimeter of 62 centimeters. if the sum of the length and twice the width is 42 centimeters, find the length of the piece of paper.

The perimeter (62 cm) is twice the length plus twice the width.

The length plus twice the width is given as 42 cm. The difference between these sums is the length, 20 cm.

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3
