Answer:
Explanation:
Area of a parellogram is bh but a parellogram with its adjacent sides equal is a rhombus and rhombuses area us 1/2diagonal1×diagonal2 also diagonal of a parellogram bisect each other so diagonal will be 8cm and 14cm diagonal of a parellogram divides it into two congruent triangle vertically opposite angles are equal all non zero numbers are significant if zero is between two numbers its significant if zero is after decimal and the number less than zero than the zeroes are insignificant like in 0.0820 but the zeroes after decimal are significant
But zeroes after no decimals are not significant like 100 the powers tens are irrelevant like 10^3 has only one significant figure
Sorry don't know answer but hopes this helps so sorry
