What will happen to the area of a rhombus if both the diagonals are quadrupled

then the answer will be multiplied by 16

Step-by-step explanation:

a rhombus with diagonals 1 and 1 will have an area of 0.5

a rhombus with diagonals 4 and 4 will have an area of 8

8 is 16 times 0.5 so the area will be the number times 16

Hope this helps :)

intensity of the vector is v= √37 ≈ 6.08 units and make angle ∡α ≈ 9.46° with east direction

step-by-step explanation:

required vector is consists of the two componentsvx= 2+4=6 units   and vy= 1 unit and vx ⊥ vywe will use pythagorian theorem to find intensity of the vector vv∧2 = vx∧2 + vy∧2 => v = √vx∧2 + vy∧2 = √6∧2 + 1∧2 = √36+1 = √37 ≈ 6.08 unitsthe angle ∡α between vector and east direction we wil find with tanαtanα = 1/6 => α = arc tanα = arc 1/6 => α ≈ 9.46°

hope this
