Step-by-step explanation:
area of kite ABCD
with diagonal BD it is divided into two equal triangle, ∆ABD and ∆CBD
area of ∆ABD = 1/2 × base × height
= 1/2 × BD × AO
= 1/2 × 51 × 17
= 25.5 × 17
= 433.5 sq cm
similarly area of ∆CBD = 433.5 sq cm
area of kite ABCD = ar ∆ABD + ar ∆CBD
= 433.5 + 433.5
= 867 sq cm
cost of manufacturing is Rs. 0.05 per sq cm
867 × 0.05 = 43.35
therefore the cost for manufacturing is Rs. 43.35
hope you get your answer
