Step 1: simplify the equation by using the distributive property where applicable and combining like trems
Step 2: Collect all the variables on one side by either adding or subtracting.
step 3:Using inverse operations for addition and subtraction can removecontants ,toget the vaiables and constants on opposite sides.
Step 4:Inverse operations, such as multiplying and dividing can be used to eliminate coefficients in front of variables to get the variables by themselves
Answer:
108 cm²
Step-by-step explanation:
Area of a rectangle, A = length, l × width, w
Perimeter of a rectangle = (2 × length) + (2 × width)
42 cm = 2l + 2w
<em>but</em><em> </em>length = w + 3cm
42 cm = 2(w + 3cm) + 2w
42 cm = 2w + 6cm + 2w
42 cm = 6cm + 4w
4w = (42 - 6) cm
4w = 36 cm
》w = 9cm
》l = w + 3cm = 9cm + 3cm
l = 12 cm
Area = 12 × 9 = 108 cm²
