Answer:
Q1) 104m²
Q2) 121 in.²
Step-by-step explanation:
<em>Q1)</em>
<u>GIVEN :-</u>
- Figure given in the question comprises of a triangle & a rectangle.
- Length of the rectangle = 10 m
- Width of the rectangle = 8 m
- Base of the triangle = 8 m
- Height of the triangle = 6 m
<u>TO FIND :-</u>
<u>GENERAL FORMULAES TO BE USED IN THIS QUESTION :-</u>
- For a triangle with height 'h' & base 'b' , its area = .
- For a rectangle with length 'l' & width 'w' , its area =
<u>SOLUTION :-</u>
Area of the triangle =
Area of the rectangle =
Area of the figure = (Area of the triangle) + (Area of the rectangle)
= 24m²+ 80m²
= 104m²
<em>Q2)</em>
<u>GIVEN :-</u>
- Figure given in the question comprises of a triangle & a trapezium.
- Lengths of parallel sides of trapezium are 6 in. & 7 in.
- Height of trapezium = 20 - 3 = 17 in.
- Base of the triangle = 3 in.
- Height of the triangle = 7 in.
<u>TO FIND :-</u>
<u>GENERAL FORMULAES TO BE USED IN THIS QUESTION :-</u>
- For a triangle with height 'h' & base 'b' , its area = .
- For a trapezium with parallel sides whose lengths are 'a' & 'b' and height 'h' , its area =
<u>SOLUTION :-</u>
Area of the triangle =
Area of the trapezium =
Area of the figure = (Area of the triangle) + (Area of the trapezium)
= 10.5 in.² + 110.5 in.²
= 121 in.²
Answer: 192
Step-by-step explanation:
3 x 8 = 24
24 x 8 = 192
8n-20=15+n
n=5
20 less than 8 times a number = 8(n)-20 same as (=) 15 more (+) than a number(n) 15+n
