Answer 1

Answer:

draw a line of 6.2 CM and then draw 80degree angle from one end of the line. then interest them.

Pls mark me as the brainliest.

Answer 2

Answer:

17 cm

step of explanation:

(i) Draw AC=6.2 cm.

(ii) Bisect AC at O.

(iii) Make ∠COX=80° and produce XO to Y.

(iv) Set off OB= 1/2(4.6)=2.3cm and OD= 1/2(4.6)=2.3cm as shown.

(v) Join AB,BC,CD and DA.

Then, ABCD is the required parallelogram.

Measure the sides of the parallelogram. The sides are of length 6.2 cm and 2.3 cm. Therefore, perimeter =2(6.2+2.3)=17cm
