Question

the area of a rectangle whose length is (x-4) units and breath is (2x+3) units is _____________

Answer 1

Step-by-step explanation:

Rectangle has the length 13 cm and width 8 cm. solve for perimeter of rectangle.

Solution:

Given that:

Length (l) = 13 cm

Width (w) = 8 cm

Perimeter of the rectangle = 2(l + w) units

P = 2(13 + 8)

P = 2 (21)

P = 42

Thus, the perimeter of the rectangle is 42 cm.

Answer 2

please mark me brainliest plzzzzzzzz

Answer:

The area of rectangle is 2x^2-5x-12.

Step-by-step explanation:

area of rectangle=length×breadth.

$= (x - 4)(2x + 3)$

$=2{x}^{2} + 3x - 8x - 12$

$= 2 {x}^{2} - 5x - 12$
