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
Answer:
9
Step-by-step explanation:
3−4x=−60+3x
Step 1: Simplify both sides of the equation.
3−4x=−60+3x
3+−4x=−60+3x
−4x+3=3x−60
Step 2: Subtract 3x from both sides.
−4x+3−3x=3x−60−3x
−7x+3=−60
Step 3: Subtract 3 from both sides.
−7x+3−3=−60−3
−7x=−63
divide by -7

Hey there!
Question #1.
36% of 400
= 36% * 400
= 36/100 * 400/1
= 36 ÷ 2 / 100 ÷ 2 * 400/1
= 18/50 * 400/1
= 18 ÷ 2 / 50 ÷ 2 * 400/1
= 9 / 25 * 400/1
= 9(400) / 25(1)
= 3,600 / 25
= 3,600 ÷ 25
= 144
Therefore, the answer should be: 144
Question #2.
16% of 32
= 16% * 32
= 16/100 * 32/1
= 16 ÷ 2 / 100 ÷ 2 * 32/1
= 8 / 50 * 32/1
= 8 ÷ 2 / 50 ÷ 2 * 32/1
= 4 / 25 * 32/1
= 4(32) / 25(1)
= 128 / 25
≈ 5.12
≈ 5 3/25
Therefore, the answer should be:
• 128/25
• 5.12
• 5 3/25
(Either of those should work because they are equivalent or equal to each other!)
Good luck on your assignment & enjoy your day!
