Answer:
x = 20.4
Step-by-step explanation:
x/0.6 = 17/0.5
0.5x = 17 (0.6)
0.5x = 10.2
0.5x/0.5 = 10.2/0.5
x = 20.4
CHECKING MY WORK:
20.4/0.6 = 34
17/0.5 = 34
34 = 34
Given is rectangle with perimeter = 54 centimeters and area = 176 squared centimeters.
Let's consider the length of rectangle = L and width of rectangle = W.
We know the following formulas for rectangle :-
Perimeter = 2 x (L + W)
Area = L x W
So we have 2 x (L + W) = 54 and L x W = 176.
L + W = 27 and L x W = 176
We need to find two positive integers such that their sum is 27 and product is 176.
Using trial and error, we have two such positive integers such that 11 + 16 = 27 and 11 x 16 = 176.
So, the dimensions of rectangle would be 11cm x 16cm.
Hence, option A is correct i.e. 11 cm by 16 cm.
Answer:
735 cm²
Step-by-step explanation:
The figure is a trapezium .The area of the triangle section can be calculated using the Heron's formula.
The other part of the figure will be a square of sides 21 cm by 21 cm
<u>Area of the square section</u>
Area = l²
Area = 21* 21 = 441 cm²
<u>Area of the triangle using Heron's formula</u>
Sides of the triangle are ;
a= 28 cm
c= 35 cm
b = 21 cm -----height of the trapezium
The Heron's formula is given as;
where s is half the perimeter of the triangle
Perimeter of the triangle is given as ;
P= 35 + 28 + 21 =84 cm
s= 84/2 = 42 cm
Total area = 294 + 441 = 735 cm²
225 pages, its correct answer i did the math
180/80
x /100
cross multiply;
180*100=18,000
divide with the amount left
18,000/80=225
