Question

answer these question
1.In triangle, base and height are 6 m and 7m respectively. Find the area of the triangle.
2. In parallelogram, pair of opposite sides are equal and parallel.
3.In a rectangle, if its length is equal to its breadth then it is called
4.Height of the parallelogram is _______ to its corresponding base. *​

Answer 1

Answer:

The measure of a height of a parallelogram is the distance between opposite sides of the parallelogram. There are two possible values for height, depending on which pair of opposite sides are chosen. The base is defined to be one of the two chosen opposite sides.

Answer 2

Answer:

Perimeter of Triangle

2S=26+28+30=84

⇒S=42cm

Area

s(s−a)(s−b)(s−c)

(Heron's formula)

Area =

42(42−26)(42−28)(42−30)

=

42×16×14×12

Area=336cm

2

Area of parallelogram = Area of triangle

⇒ h×28=336

⇒h=12cm

Height of parallelogram =12cm
