Question

3. Find the perimeters of the following.
(a) Parallelogram whose length is 12 cm and breadth is 7 cm
(b) Rhombus whose length is 8 cm And
4.find the length of the missing sides of the following figure.​

Answer 1

Step-by-step explanation:

$3. \: (a) \: perimeter \: of \: parallelogram = 2(12 + 7)$

$24 + 14 = 38cm$

$(b) \: perimeter \: of \: rhombus = 4 \times 8 = 32cm$

$4. \: let \: the \: both \: side = x$

A/Q

$x + x + 4.6 = 7.6 \\ 2x = 7.6 - 4.6 \\ x = \frac{3}{2 } \\ x = 1.5cm$
