2. State whether the following are true or false:
(0)
The area of a rectangular field measuring 50 m by 15 m is 750 m2
(ii) The perimeter of an equilateral triangle with each side 5 m long is 25 m2
(iii) If the side of a square measures 2 cm, its perimeter is 8 cm.
(iv) The area of a rhombus is calculated by dividing it into two rectangles.
(v) To calculate the area of a triangle, we need to know the lengths of its
base and height.
Answers
Answer:
Required Answers :-
1)
Area of rectangle = Length × Breadth
750 = 50 × 15
750 = 750
2)
Perimeter of equilateral triangle = 3a
25 = 3(5)
25 ≠ 15
3)
Perimeter of square = 4s
8 = 4(2)
8 = 8
4)
Yes,
Example :- Let's say the diagonal of rhombus are 6 and 8 m
Now,
Area of rectangle = 6 × 8 = 48 m
Area of rhombus =48/2 = 24 m
5)
Yes,
By knowing the base and height of triangle we can find area of triangle. As area of triangle is ½ × Base × Height
Hence :-
- True
- False
- True
- True
- True
Step-by-step explanation:
SOLUTION:-
1) AREA OF RECTANGLE = Length × Breadth
750 = 50 × 15
750 = 750
2) PERIMETER OF EQUILATERAL TRIANGLE = 3a
25 = 3(5)
25 ≠ 15
3) PERIMETER OF SQUARE = 4s
8 = 4(2)
8 = 8
4) THE DIAGONAL OF RHOMBUS ARE 6 AND 8m
AREA OF RECTANGLE = 6 × 8 = 48 m
AREA OF RHOMBUS = 48/2 = 24 m
5) WITH THE BASE AND HEIGHT OF TRIANGLE WE CAN FIND AREA OF TRIANGLE.
AREA OF TRIANGLE = ½ × Base × Height
So,
.True
False
True
True
True
