Can someone please help me with this question? Thanks.

Answer 1

Answer:

$(24x+40) \: cm^2$

Step-by-step explanation:

Area of rectangle is $lw$

$8 \times (3x+5)$

The length is (3x+5) cm.

The width is 8 cm.

$8(3x+5)$

Expand the brackets.

$8(3x)+8(5)$

$24x+40$

Answer 2

Area = length x width

Area = 3x + 5 Cm x 8 cm

Multiply each term by each term.

Area = 24x + 40 square cm
