Question

PLEASE ANSWER I WILL MARK AS THE BRAINLEAST

Answer 1

answer;15/4

Perimeter of a rectangle = 13 cm

width=11/4

2(length+breadth) = 13

length + 11/4 = 13/2

length = 13/2 - 11/4

length = 26/4 - 11/4

length = (26-11)/4

length = 15/4

Therefore, length of the rectangle = 15/4 cm

Answer 2

Answer:

let the length(l) of the rectangle be x

width = b = $2\frac{3}{4}$

Perimeter = 13 cm

thus

$2(l + b) = 13\\\\2(2\frac{3}{4} + x ) = 13\\\\(\frac{11}{4} + x) = \frac{13}{2}\\\\(\frac{11 + 4x}{4}) = \frac{13}{2}\\\\11 + 4x = 13 * 2\\\\11 + 4x = 26\\\\4x = 15\\\\x = \frac{15}{4}\\\\x = 3\frac{3}{4}$

therefore length = $3\frac{3}{4}$ cm
