The expression ( l \times w ) typically represents the area of a rectangle, where ( l ) stands for the length and ( w ) stands for the width. By multiplying these two dimensions, you calculate the total space contained within the rectangle. This formula is commonly used in geometry and real-life applications involving rectangular shapes.

How do I write an expression For the area of each rectangle into different ways then find the area using each expression?
To write an expression for the area of a rectangle, use the formula (A = l \times w), where (l) is the length and (w) is the width. You can express this in different ways, such as (A = w \times l) or (A = l^2) if it's a square where (l = w). To find the area, simply substitute the values of length and width into your chosen expression and calculate the result. For example, if (l = 5) and (w = 3), then (A = 5 \times 3 = 15) square units.
In math if you have a length and it is 8 and width is 11 what is the perimeter and area?
P = 2 (L + W) and A = L x W
What does each of the variables in these formulas represent?
It can represent formulas like A=L×W etc...
When a rectangular sheet of metal is heated its length and breath increase by 10 percent Calculate the overall percentage increase in area?
21% Area = length*width Let Aoriginal represent the original area and Aheated represent the area of the rectangle after heating. Let l and w represent the original length and width of the rectangle. Because l and w increase by 10% on heating, we have the following: Aheated = (1.10*l)(1.1*w)=1.21(l*w) Because Aoriginal = l*w, Aheated =1.21(l*w)=1.21*Aoriginal So the area of the rectangle increases by 21% upon heating.
How do you simplify an expression for the perimeter and area of a rectangle?
Represent the length of the rectangle by L and the width by W. The perimeter = 2L + 2W = 2(L + W). The area = L x W.

w=width

How do you write one tenth of w in a algebraic expression?
To write one tenth of w in an algebraic expression, you can use the expression (1/10)w or w/10. Both of these expressions represent dividing w by 10, which is equivalent to finding one tenth of w.

How can you use the distributive property to write an equivalent expression for 2l plus 2w Explain?
You can use the distributive property to factor the expression (2l + 2w). By factoring out the common factor of 2, you can rewrite the expression as (2(l + w)). This shows that the sum of (2l) and (2w) can be expressed as twice the sum of (l) and (w).
